Application filed September 11, 1917. Serial No. 190,832.

To all whom it may concern:

Be it known that I, HERBERT E. RIDER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Vaporizin Tubes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

his invention relates to oil burners, and more particularly to that type of burnerin which the heavier hydrocarbon oils may be employed as fuel.

It has for an object to provide an imroved retort in which accumulation of caron is prevented.

' A further object of the invention is to piqovide a retort of simple construction containing means operable by changes of temperature to prevent such accumulation of carbon.

Further objects will be apparent from the appended claims, in which:

Figure 1 shows the complete apparatus as applied to a steam boiler, illustrating parts of the boiler and fire box broken away, Fi 2 shows in section, a portion of the supply line,

Fig. 3 is a perspective view of a small portion of the vaporizing tube showing the shell removed from a section of the rods,

Fig. 4 is a perspective view of a rod removed, and,

Fig. 5shows an enlarged perspective view or the vaporizin tube in cross section, and

Fig. 6 is an en arged sectional view of the fastening of one end of the rods. In this invention, the retort and burner may be considered as for use with such heavy hydrocarbons, as precipitate carbon, upon heating to vaporize. The apparatus is intended to receive the heavy oil, feed it in proportions suficient to create the desired heat units for generatin steam or for other heating purposes, to re uce the oil to a vapor which is fed to the burner, and to maintain a free passage through a vaporizing coil by dislodging the carbon precipideposits through action of certain parts of the apparatus.

Referring more specifically to the drawings, there is shown a steam boiler 10 having an oil burner placed in the fire box and this burner plurality of burner tubes 11 which have sections of a distributing duct 12 formed thereon. These burner tubes are secured to'each other, with the sections 12 formlng a continuous duct, and

intermediate burner tubes may be included to build up a burner of the desired capacity. The central duct section 12 has a depending nipple 13 which forms an admission inlet for a gaseous mixture, and below this opening, a nozzle 14 is placed. This nozzle is provided with a needle valve actuated by the hand wheel 15 on the valve stem, and one end of a retort 16 is connected to the nozzle as by the coupling 17.

The retort 16 comprises a thin shell in which, rods or wires 18, 19 and 20 are snugly fitted. he rods are corrugated, or roughened and are of difi'erent metals, so that when changes of temperature occur, the individual rods will expand or contract in different ratios, and owing to the relative movement, they will dislodge any carbon deposits which would otherwise tend to form and accumulate. The corrugations in these rods form abrasive surfaces which keep the interstices between the rods and inner wall of the shell clean for the free passage of oil. I

The retort 16 head, so that oil passing through this retort will be heated to convert it into a vapor. The other end of this retort is secured in a fitting 21 which is shown as a T, having an oil supply pipe 22 attached to the branch, and having thev proximal ends of the rods 18, 19 and 20 enter the extension, where they are brazed or otherwise secured as suggested in Fig. 6 but havin the extreme end closed against the escape oil. By fasten is coiled over the burner lid till

ing the ends of these rods, the expansion oi? the individual rods is utilized, but a tree passage for the oil is retained through the interstices between the rods, and within the shell. In placing the rods in close bearing relation, heat is readily conducted into the interior of the tube to convert the oil into a vapor, and the corrugated or interrupted surfaces form passages communicating between the several interstices.

The oil supply pipe 22 is provided with a pressure controlled valve comprising the chamber 23 with a diaphragm 24 therein, and this diaphragm is attached to a valve 24' which controls chamber is connected with the steam dome of the boiler as by the pipe 25 and through an adjusting means A, any boiler pressure may be adapted to reduce the oil supply.

Should the supply pipe become separated or should the oil supply flow at a greater velocity than is necessary for the burner, an automatic check valve 26 in the casing 27 seats and closes the passage through the pipe 22. A spring and adjusting nut will afiord adjustment of this valve to regulate a normal flow, but any excessive flow will automatically seat the valve,

- The pipe line 22 is connected with and extends into an oil tank 28 to a point near the bottom or it may be connected with the tank near the bottom. This tank is further provided with a gage 29 for determining the, air pressure and with a source of air pressure as through the pipe 30 and air pump 31. The tank also has a filling opening which is closed as by the cap 32. manually operated valve 33 may serve to cut 0d the oil supply when desired.

It is thought that the operation of this device is obvious from the foregoing, and it is clearly seen that for use in connection with a steam boiler, alter the requirements necessary in starting the operation have been carbe established,

ried out, the oil suppl When the burner is y y and the burner started. in operation, the retort serves to convert the heavy oil into a gas which along with air is fed to the burner through the admission inlet 13. By heating the retort, and allowing it to cool, the expansible rods will serve to convey heat into the retort, and also keep it clean.

Adjustment of the pressure operated valve and check valve may be made when the working conditions of the apparatus have been established, and by the desired air pressure, a uniform flow of oil may be obtained through the retort. The indications of iron, brass, and copper for the rods 18, 19 and 20 are used only to indicate that metals having difierent coeiiicients of expansion are employed and are not intended to the oil feed. The upper neeacor indicate that the invention is limited to the use ol these three metals.

Other modifications may be made in view of the appended claims without departing "from the spirit of this invention, and the drawings are'for illustrative purposes only.

3. In an oil burner of the class described, a retort comprising a tube, and a plurality of continuous rods snugly placed therein secured at one end in said tube, and being of difi'erent metals having different coeillcients of expansion, said rods being corrugated to prevent accumulation of carbon on said rods and in said tube.
